PSR-2 started indent with two spaces

Something happened between b67b34c43c6e937b70fcf87cc324936ef117093b (works fine) and 2c83fbe9af2ac07806e973ed6baa34582fb70f4e (newer one but doesn't work fine) that breaks my PSR-2 indentation.

```php
<?php
namespace Lib;

class MyClass
{
    function myFunction()
    {
    // Pressing tab here will place this line indented at six spaces from "zero" instead of eight.
    }
}
```
